Change size of axes title and labels in ggplot2

ggplot2, r

Solution

You can change axis text and label size with arguments `axis.text=` and `axis.title=` in function `theme()`. If you need, for example, change only x axis title size, then use `axis.title.x=`.

g+theme(axis.text=element_text(size=12),
        axis.title=element_text(size=14,face="bold"))

There is good examples about setting of different `theme()` parameters in ggplot2 page.

Problem

I have a really simple question, which I am struggling to find the answer to. I hoped someone here might be able to help me. An example dataframe is presented below: ``` a <- c(1:10) b <- c(10:1) df <- data.frame(a,b) library(ggplot2) g = ggplot(data=df) + geom_point(aes(x=a, y=b)) + xlab("x axis") g ``` I just want to learn how I change the text size of the axes titles and the axes labels.
